Application filed July 19, 1917. Serial No. 179,702.

To all whom it may concern:

Be itknown that I, HENRY W. MULLENAX,

a citizen of the United States, residing a Monterey, in the county of Highland and State of Virginia, have invented a new and useful Convertible Hillside Reversible Plow, of which the following is a specification.

The invention relates to a convertible hillside reversible plow.

The primary object of the invention is the provision of a plow of this character, wherein on adjusting the double mold-board of the same, an auxiliary mold-board can be positioned so that the plow will be converted from a hillside to a level land or other plow, thereby permittin the working of any character of ground and particularly level ground or a hillside, the plow being readily adjusted to convert the same for the particular use required, and the reversing of its mold-board can be easily effected with despatch, without raising or upsetting the plow.

Another object of the invention is the provision of a plow of this character, wherein the construction thereof is novel in form to assure the convenient adjustment of the same and the perfect working thereof for the positive turning of earth on level or grade surfaces, the plow being readily movable from' one point to another without throwing it upon its side as usual, when desired to transfer said plow from one field to another.

A further object of the invention is the provision of a plow of this character, which is comparatively simple in construction, thoroughly reliable and efficient-in its operation, readily and easily adjusted, strong, durable, and inexpensive in manufacture.

Other objects will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, the combination of elements and arrangement of parts, which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings Figure l is a side elevation of a plow constructed in accordance with the invention, the plow being partly broken away.

Fig. 8 is a plan .view of the foot pedal and catch arms for the reversible mold-board.

Fig. 9 is a plan view of the double right and left hand mold-board and point.

Similar reference characters designate like parts throughout the several figures.

Referring to the drawings in detail, A designates the main or draft beam, B the standard, C the forwardly directed runner, D the double right and left hand mold-board, and E the handles of the plow, the essentialdetailsof which will be hereinafter fully described.

On the main or draft beam A of the plow at the front end thereof is the usual clevis hanger 10, while spaced rearwardly of the front end of said beam and secured to its under side is a bearing 11 for the mounting of the adjusting device for a'traction wheel 12. The wheel 12, when adjusted permits the dipping of the plow for varying the depth of cutting action thereof, and also allows the plow to be transported from one point to another, without necessitating the turning of the plow upon either side thereof, during the transfer or moving thereof from one field to another, as is usual. The adjusting device for the wheel comprises a leg 13, in which is journaled the wheel 12, and this leg is swingingly supported upon a pivot 1% mounted in the bearing 11 for the vertical adjustnent of said wheel, and is formed with an arm extension 15, straddling the beam A to which is loosly connected the forward end of an actuating rod 16, having its rear end pivotally connected to a throw lever 17 pivoted at 18 on one side of the beam A for swinging movement, the lever being provided with a hand release latch pawl 18 for locking engagement with a segcause the adjustment of the wheel 12' for'the raising and lowering thereof in the use of which are united to each other in any de sirable manner. The point 24, is formed w th a suitable socket for receiving the trunn on 22, whileat the inner faces of the wings of the double mold-board are.

eyes 25 in-which engage the hook ends 26 of a Y-shaped' brace 27, which is pivotallyengaged with the rear trunnion 23 and carries a swinging latch hook 23, pivoted thereto which engages with a keeper 29 mounted on the inner side of the moldboard 25', as is clearly shown in Fig. 3 of "the drawings, and in this manner, the moljd-board is detachablyfastened for the pivotal mounting thereon upon the runner. The pivotal mounting. of the mold-board permitsthesame to be swung from the right hand side to the left hand side of the plow, for the reversing thereof when used as a hillside plow The outer faces ofthe side wings of the mold-board 25 forwardly thereof are formed withfeurvilinear depressions 30 which constitute seats for an auxiliary moldboard employed for converting the hillside plow into a level land plow, in a manner to be hereinafter fully described.

The auxiliary mold-board comprises a plate, 31, preferably of the shape illustrated in Fig. 1 of'the'drawings, having a stem or standard 32, which is passed through a suitable opening 33 formed in the beam A for sliding and rotary movement on the adjustment of the auxiliary mold-board,-

the stem or standard 32 rises above the beam A and has loosely fitted thereon a sleeve 34, which is formed with a rearwardly inclinedsegment 35, and passed transversely I through this sleeve 34 is a coupling pin 36, which engagesin a circumferentialam nular groove 37 formed in the stem or standard, 32, so thatthe latter will be swiveled for rotation within the sleeve. Pivotally connected to the coupling pin 36 is the yoke end38 of the adjusting arm39 of a throw lever- 40, which is swingingly supported on thepivot 18, the latter serving, the dual function ofa pivot for both of the'levers' '17 and, 40, hereinbefore, descr"ibed. The

lever'jegqear ie al lland 're asedlawh pawl 41, wh1th engageswith a' segment 42::pro

vided with notches 43 at the proper intervals apart to receive the pawl 41, and in this manner, the auxiliary mold-board can be locked in adjusted position, either raised out of the path of reversing movement of the mold-board 25 or in lowered position for engagement with the seats 30 therein, which extend in forwardly divergent relation from the crest of said moldboard 25 through the outer edges thereof, and when the auxiliary mold board 31 is thus engaged, it forms a continuation ofthe mold board 25, to insure the turning of the earth when the plow is working in level land; The seating of the auxiliary, mold-board 31 in the reversible mold-board 25, when either atthe right hand side or left hand side of the plow, effects a smooth surface throughout the mold-boards 25 and 31, and this auxiliary mold-board, when ,in said position, will have its edge at the juncture thereof with the double mold-board 25 in contact, so that the outer surfaces of said parts will be flush with each. other; Suitablyfixed to the standard or stem 32 .of

the auxiliary mold-board 31 above the sega ment 35 is a handle or lever 44 for turnposition held fast in its set relation to the reversible mold-board.

Pivoted on the standard B at the rear end thereof is a pedal 47 to which are loosely connected catch arms 48 having forked catch extremities 49 for engagement.

with the arms of the.Y-shaped brace 27 to lock the double mold-board 25 in its reversed .positions,i-the pedal 47 beingaccess'ible for engaging the foot of the operator ,7 ofthe plow therewith to 'lock and unlock the double mold board; Thearnis 48 are slida'blethrough suitable guides 50 on the standard 13 of the'plow when the arms are moved for the latching or unlatchingof the double mold-board.

Suitably supported on the standard Bis a resilient latch 51, which engages with a; toothed segment 52 on the pedal 47 to lock the pedal in adjusted position.

In the working of the plow, 1t is obvious that the double ll'lOlCl-bOEIICl 25 can be re;

versed to either side, thereby converting the plow into a right hand or atleft -rhand hill-* side plow.-- New, when it is desiredto'com" Y t; that r awit W k i1? bie an the; mold-board 24" is adjust d- 13Q3eithe;r;. side 1 and to permit this, the auxiliary mold-board 31 is raised above the path of movement thereof, by actuating the throw lever 40, and thereafter said auxiliary mold-board 31 is brought into contacting relation to the adjusted double mold-board 25 for the engagement of the auxiliary mold-board 31 in either seat 30, and this is accomplished by the lowering of the auxiliary mold-board from its raised position and rotating the standard or stem 32 thereof to bring the said board into its proper adjusted position.

The reversible double mold-board 25 and the auxiliary mold-board 31, when properly adjusted, are locked in rigid relative positions with respect to each other for the employment of the plow in the working of level ground. Therefore, it will be clearly ob vious that the plow is readily convertible from a hillside to a level land plow, or vice versa, and such plow will turnv any character of earth in the operation thereof.

From the foregoing, it is thought that the construction and manner of operation of the invention will be clearly understood, and,

therefore, a more extended explanation has been omitted.
